Founding of Mossad
In July 1949, Shiloah proposed to Ben-Gurion the creation of a "central institute for coordinating intelligence and security services" to improve intelligence coordination. On December 13, 1949, this body was established and named the "Coordination Bureau." It oversaw the Political Department and was supposed to coordinate the activities of the other two bodies –
Shabak and
AMAN (the IDF's intelligence branch). The new organization was still under the Foreign Ministry. In March 1951, the final organizational step in its creation took place. With Ben-Gurion's approval, an independent central authority was established to handle all foreign intelligence activities. This authority, known as "The Authority," formed the main part of what became

At this time, Shiloah also served as the Director of Intelligence Services.
